## Overview <a href="#overview" id="overview"></a>

### IBM Watson STT Service <a href="#ibm-watson-stt-service" id="ibm-watson-stt-service"></a>

#### Pros:

* 16 hours a month included in service. 0.02 cent a minute after that [see pricing](https://console.ng.bluemix.net/catalog/services/speech-to-text).
* Speed. In autoEdit, always takes 5 minutes to transcribe any duration of audio or video.
* Generally pretty accurate (my opinion, judge for yourself)
* Supports a number of languages [see here](https://console.ng.bluemix.net/catalog/services/speech-to-text). Including distinction between British and American English.

#### Cons:

* Need to provide card details for pay as you go fee.
* is in the cloud so no offline support.

### Speechmatics STT Service <a href="#ibm-watson-stt-service" id="ibm-watson-stt-service"></a>

* 1 hour free credit with new account&#x20;
* Easy to setup credentials&#x20;
* Generally pretty accurate (my opinion, judge for yourself)
* [28 languages, see full list](https://www.speechmatics.com/language-support/) Including support for "accent agnostic global english".

### AssemblyAI STT Service <a href="#ibm-watson-stt-service" id="ibm-watson-stt-service"></a>

* &#x20;Free tier: 5 hours free per month
* Competitive pricing at $0.0003 per second
* Easy to setup credentials&#x20;
* Generally very accurate (my opinion, judge for yourself)
* For now only support for English but more coming soon

### Gentle Open Source STT <a href="#gentle-open-source-stt" id="gentle-open-source-stt"></a>

#### Pros:

* Free as in free speech as well as in free beer.
* Working locally on your machine. No internet connection needed because of that, good for sensitive material.
* Open source [github repo](https://lowerquality.com/gentle) and [I made a node module to work with the API](https://github.com/OpenNewsLabs/gentle_stt_node) .

#### Cons:

* Not as accurate as IBM one (in my opinion, but decide for yourself).
* Only support US english STT.
* In autoEdit, at the moment not as fast as IBM one, takes a little longer then the length of the media. (eg 27 min takes 30 min to transcribe).

[Check out for extra setup instructions for Gentle](https://github.com/pietrop/autoEdit_2_user_manual/tree/d5c8cea5ec4e2a1cee11515e8a838d832407badc/setup-stt-apis-gentle.md).

  .

#### Cons:

* Not as accurate as IBM or Gentle.
* Only support US english STT.
* in autoEdit, at the moment not as fast as IBM one, takes a little longer then the length of the media. (eg 27 min takes 30 min to transcribe).
